Hey everyone, I thought it would be interesting if a thread was made for fossils we have found most recently whether that be in situ and posted the day after the trip or if you find something new while going through matrix or concretions you may have brought home.
I'll start it off, here is a snail and baculites I found today when cracking into some of my Pierre shale material from Wyoming.

Help please. Some time ago. there was a thread in which some one I believe from the northeast USA commented on their finding various shark egg cases. I have tried searching in vain to locate that post. I volunteer at the Natural History Society Of Maryland. I am trying to put together a display/talk for shark week coming up in July. Would like to include recent shark egg cases along with my collection of fossil shark teeth and centra. I can trade various Miocene/Pliocene fossils, St Clair ferns or other fossils. Any help to connect me to anyone with shark egg cases would be greatly appreciated

It genuinely is my distinct pleasure to feature this pretty rare PDF and its few, but VERY nice images of overgrowth competition and sclerobiosis.
Worth your time? You bet.

I have 3 specimens of Recent asteroids as a comparative material to my fossils. Is there a place on the internet where I could have them identified? I suspect they are oreasterids: Pentaceraster and possibly two species of Protoreaster, but I'm not sure if really and what species.

After this horrendous attempt at a triple pun,things can only deteriorate,right?
The list of species in the tags i have kept to a bare bones minimum,for clarity's sake
i MIGHT not have posted this,but it figures tooth rows.
Shark cognoscendi prolly already have this one(and the others by Bass)I'm sure.
SO,no need to post those others

Hi all,
my grandpa recently gave me this snail shell he brought from a Florida holiday some decades ago (he said he "pulled it out of the ocean"; but that's all details I have on the finding situation).
I saw this post by Herb with Florida shells, one of which looks quite similar:
For the one in my images I'm wondering whether it is a recent exemplar or a fossil one. In a German fossils forum where I showed the images someone tended to recent because of the slight color remnants.
On the other hand, it looks really similar to the fossil busycon contrarium I saw here: https://en.wikipedia.org/wiki/Busycon_contrarium
Any hints regarding recent vs. fossil and more specific ID are highly welcome!
The Euro coin for scale is about 0.9 inch in diameter.
Many thanks in advance

P.S.: Very nice forum you have here!

I'm fairly certain this is a humerus, but to what? I am a herpetologist and spend a lot of time along rivers. I came across this today as I was searching for frogs, and I decided to hang on to it to ID it. So far, I have been unsuccessful and I assume you guys are way better at this than me. The bone/fossil doesn't feel as heavy as most fossils I have come across, but it is definitely heavier than bone. It is completely black underneath the crispy tan layer shown in the photographs. It was found in an area along the river bank that had recently been washed out due to recent rains. So I'm not certain if it originated high above the bank or in the wet sand.
Thank you,
Buddy
